BC817-25W-7 Description

Short technical summary and product information.

The BC817-25W-7 is a 45V NPN small signal transistor manufactured by Diodes Incorporated. It features a continuous collector current rating of 500mA and a peak current of 1A, making it suitable for switching and amplifier applications. The device offers a DC current gain (hFE) of 160 minimum at 100mA, 1V, and a transition frequency of 100MHz.

 

This transistor is housed in a compact SOT323 surface mount package, which is ideal for automatic insertion and high-density PCB designs. The package is made of green molding compound with UL94V-0 flammability rating, and the leads are matte tin plated for solderability.

 

The BC817-25W-7 is qualified to AEC-Q101 standards for high reliability automotive applications. It is fully RoHS compliant, lead-free, and halogen and antimony free. The device has an operating temperature range of -65°C to 150°C and a power dissipation of 200mW. With ESD ratings of 4kV HBM and 400V MM, it offers robust protection in handling.

 

This transistor is complementary to the PNP type BC807-xxW. It is supplied in tape and reel packaging with 3000 pieces per reel, suitable for automated assembly processes.
